Configuring the Rapid PVST+ Port Priority—CLI Version
You can assign lower priority values to LAN ports that you want Rapid PVST+ to select first and higher
priority values to LAN ports that you want Rapid PVST+ to select last. If all LAN ports have the same priority
value, Rapid PVST+ puts the LAN port with the lowest LAN port number in the forwarding state and blocks
other LAN ports.
The device uses the port priority value when the LAN port is configured as an access port and uses the VLAN
port priority values when the LAN port is configured as a trunk port.
Before You Begin
Ensure that you are in the correct VDC (or enter the switchto vdc command).
